For more than eight years, scientists using the two instruments on the Fermi Gamma-ray Space Telescope have gained significant experience with monitoring the high-energy Universe. The Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) have huge fields of view, and Fermi operates in a scanning mode, allowing the entire gamma-ray sky to be viewed about every three hours. Most of the...

The High Altitude Water Cherenkov (HAWC) observatory is a wide field-of-view
gamma-ray detector that performs monitoring of two thirds of the sky
every day at energies between 0.1 and 100 TeV.
Operating in its full configuration since March 2015, with a duty cycle of
approximately 90%, HAWC has already accumulated an unprecedented data set of unbiased and
evenly sampled daily TeV light...

The Very Energetic Radiation Imaging Telescope Array System (VERITAS), located in southern Arizona USA, is an array of four 12-m diameter imaging atmospheric-Cherenkov telescopes dedicated to studying the very-high-energy (VHE, E > 100 GeV) gamma-ray sky. The investigation of Active Galactic Nuclei (AGN) is a key element of the VERITAS long-term science plan, with 34 detected by VERITAS to...

A key project of the High Energy Stereoscopic System (H.E.S.S.) is the regular monitoring of different types of blazars at very high energies (E>100 GeV). Since the inauguration of H.E.S.S. in 2004 the high-frequency peaked BL Lac object PKS 2155-304 and the radio galaxy M 87 have been observed frequently. The flat spectrum radio quasar PKS 1510-089 has been added to the list of monitored...

Classical Novae were revealed as a surprise source of $\gamma$-rays in *Fermi* LAT observations. During the first 8 years since the LAT was launched, 6 novae in total have been detected to $ > 5\sigma$ in $\gamma$-rays, in contrast to the $69$ discovered optically in the same period. We attempt to resolve this discrepancy by assuming all novae are $\gamma$-ray emitters, and assigning peak...

The First G-APD Cherenkov Telescope (FACT) is pioneering the usage of solid state photo sensors (G-APD aka SiPM) for measuring the dim flashes of Cherenkov light initiated by the interaction of a high energetic particles or photons with the atmosphere. One advantage of these sensors is that they donot degrade even when exposed to bright light. Therefore, FACT can operate with standard setup...

The COMPTEL experiment aboard Compton Gamma-Ray Observatory (CGRO) explored the MeV sky (0.75 - 30 MeV) for more than 9 years between April 1991 and June 2000, providing a wealth of discoveries. Now, more than 16 years after the deorbit of CGRO, the COMPTEL data are still the forefront of our knowledge on the non-thermal soft gamma-ray sky (1 - 30 MeV), because no successor is operating....
